Heat index

The heat index value during March is computed to be a life-threatening hot 53°C (127.4°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
